provements in carding devices for artificial teeth. The primary objectof the inventlon s to provide an article of this character so con- I needed, the removal and replacement of the teeth from the base being easily and quickly accomplished without marring the work- 'ing surfaces of the teeth.

A further-object of the invention is to provide'an article of this character so constructed that the'respective teeth will be resiliently retained on thebase to prevent accidental disengagement therefrom, 1 but are capable of beingeasily removed and replaced. V e 5 l/Vith these and other objects in view,-as will appear as the description'proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointedl out inthe appended claims. p

In the accompanying drawing: f V

V Figure 1 is a front elevation of the" device," Figure 2 is a. transverse sectional View sired new i should it be necessary;

through the same, and f l Figure 3 is a horizontal sectional view.

Referring to the drawing, 1 designates a base rectangular in shape and preferably formed from wood, but it will be of course understood that anyother material suitable for 'the purpose may be used.

The base has driven or otherwise suitably secured thereto a plurality of aligned studs 2, which are spaced equal distances apart and have their upper ends provided with substantially circular heads 3, which are disposed transversely of the base 1 and are shaped to conveniently fit the slots 4: in the V artificial teeth 5, these teeth as usual having flat inner faces 6.

An elongated metallic retaining strip 7 is employed and is formed with aplurality of cut outs 8 whereby a plurality of resultant bridge pieces'9 are produced, said bridgepieces beingcurved transversely to the lon- :gitudinal axis of the strip. The bridge pieces c, A 3, 15 com any, or conumausoi'rro, aconron irro'n the teeth,

are pleaded with slots 10 through 'which the studs2- tive bridge pieces." It will be observed that when the strip is engaged "with the base 1 and the slots 4 ofthe teeth are engagedby the studs and hea'd sthat the bridge piecea-idue to their curvature, exert an outward pressure upon the flat side --6 of the teeth, therebyholding the same yieldablyiinterlocked with saidstuds.

The slots 4 ofthe teeth haveone of'their ends terminating near. the cutting edge 'of while'the other ends of said slots open at the opposite endsof said teeth, and

in view of this fact the teeth can be easily them against accidental disengagement from v if the studs.

-It will be of course obviousthat to remove V the teeth it is only "necessary'to place the attached to the base by simply placing the finger f'the'reon and :move' the same trans- I readily removed from the base 1 when no teeth are in place thereon, therefore if de strips can be Thejhe'ads 3of the stud areof such contour that they can pass freely into theslots in alongitudinal direction, but can not disengage thesame in a lateral direction.
